Thesis Details

In this research work, cellulose acetate filament yarns have been cyclically loaded to different extents and subsequently dyed for different time periods. Then these dyed yarns were anlyzed for dye take-up in an effort to relate previous conditioning of the yarn to the dye take-up.
It has been shown that the dye take-up and dyeing rate of cellulose acetate filament yarn is sensitive to each of three factors: 1) number of cycles; 2) rate of loading, and 3) magnitude of ull load to which the filament yarn had been previously subjected.
It is thought that this work sheds a revealing light upon many dyeing defects met with in mill practice.
